two thoughts on wrong.
first, make sure using correct gradle dependency:
compile 'com.android.support:design:22.2.0' second, make sure activity extending appcompatactivity , not activity or actionbaractivity.
you can read full post more details, here's relevant quote needing appcompat new support design library:
note design library depends on support v4 , appcompat support libraries, included automatically when add design library dependency.
if want know why, can read this or this more background android's new "preferred" way of handling callbacks, using appcompatdelegate.
